OROVILLE — One of the largest marijuana refining labs ever encountered by Butte County sheriff's investigators was discovered Thursday when a warrant was served at an address on Spur Court in South Oroville.

The lab was found after detectives in the sheriff's Special Warrant Unit arrived at the location at around 9:20 a.m. with a search warrant.

One person was found at the property. Kelley Lawrence Trousdale, 34, of Aptos, was detained without incident, authorities said.
